Polyglykol G 500 is a very low VOC humectant for waterborne pigment preparations.
Polyglykol G 500 provides lower preparation viscosities compared with conventional linear polyglycoles and has little impact on wet scrub resistance. Polyglykol G 500 retards the drying of pigment pastes and forms a soluble film of the pigment preparation. It prevents the formation of skin or lumps on the surface of the dispersion.
The dosage in pigment preparations varies from 5 – 15% in the preparation.
